A New Classification System To Describe the Ageing of Scientific Journals and Their Impact Factors.

Moed, H. F.; Van Leeuwen, Th. N.; Reedijk, J.

Journal of Documentation, v54 n4 p387-419 Sep 1998

Aging patterns are examined in "formal" use or impact of all scientific journals processed for the "Science Citation Index" during 1981 to 1995. A new classification system of journals in terms of their aging characteristics is introduced. It is shown that the cited half-life, printed in the "Journal Citation Reports," is an inappropriate measure of decline of journal impact. (Author/AEF)
